一 kickstart简介

ks是自动批量安装工具，它可以从网络自动安装操作系统，不需要与用户交互，对于需要安装大批量机器，可以很方便快速的安装和使用。

相关变量参数详解：

%packages 定义需要安装的包裹

%pre 预先安装

%post

ks配置文件详解：

url --url=" 指定URL

vnc --password=redhat

clearpart: clears the specified partitions before installation.

clearpart --all --drives=sda,sdb --initlabel

part : specifies the size,format,and name of a partition.

part /home --fstype=ext4 --label=homes --size=4096 --maxsize=8128 --grow

ignoredisk : ignores the specified disks when installing.

ignoredisk --drives=sdc

bootloader: defines where to install the bootloader.

bootloader --location=mbr -boot-drive=sda

volgroup,logvol: creates lvm volume groups and logical volumes.

part pv.01 --size=8192

volgroup myvg pv.0.1

logvol / --vgname=myvg --fstype=xfs --size=2048 --name=rootvol --grow

Network commands:

#启动网络配置为dhcp

network --device=eth0 --bootproto=dhcp

#启动防火墙

firewall --enabled --service=ssh,cups

#配置语言为utf8

lang en_US.UTF-8

#键盘

keyboard --vckeymap=us --xlayouts='us','us'

timezone --utc --ntpservers=time.xxx.com Europe/ASIA

#root密码

rootpw --plaintext redhat

selinux --enforcing

services --disabled=network,iptables,ip6tables --enabled=firewalld

group --name=admins --gid=10001

user --name=cw --gecos="chen wei" --groups=admins --password=chenwei --plaintext

loggin --host=www --level=info

firstboot --disabled

检查语法工具：ksvalidator ks.cfg

二安装配置

1.需要安装的有：

Network servers:FTP,HTTP,NFS

DHCP/TFTP SERVER

USB disk or CDROM

local hard disk

2.启动方式：

ks=

ks=nfs:server/dir/file

ks=cdrom:/dir/file

三案例

使用system-config-kickstart工具，创建一个配置文件

#############################################################

一 tftp配置用于pxe启动

二 dhcp配置

三 kickstart文件配置

四 yum服务器

通过选择安装不同的linux。

比如：安装rhel6/rhel7等等

=============================================================

一环境说明：

1.1 环境是

RHEL5.7 64

dhcp服务器 : 要求可以正常分配ip并且指定TFTP服务器

vsftp 服务器 : 用于存放 Yum 仓库

tftp 服务器 : 存放系统安装所需要的引导文件pxelinux.0文件、启动菜单、内核vmlinuz及initrd.img、ks无人值守配置文件ks.cfg

pxelinux.0 pxe专用启动引导文件，/usr/share/syslinux 目录中找到,直接存放在TFTP要目录即可（也可在/etc/dhcpd.conf 指定）

客户端需要

支持PXE启动的网卡

具体过程

建好Yum源，vsftp/PXE 启动的准备工作

二安装步骤：

2.1 tftp安装配置

cd /var/lib/tftpboot/

[root@chenwei tftpboot]# cp /usr/lib/syslinux/pxelinux.0 .

[root@chenwei tftpboot]# ls

linux-install pxelinux.0

[root@chenwei tftpboot]# mkdir pexlinux.cfg

[root@chenwei tftpboot]# cp /opt/yum/pub/isolinux/isolinux.cfg pexlinux.cfg/default

[root@chenwei tftpboot]# cp /opt/yum/pub/p_w_picpaths/

boot.iso diskboot.img minstg2.img pxeboot/ README stage2.img TRANS.TBL xen/

[root@chenwei tftpboot]# cp /opt/yum/pub/p_w_picpaths/pxeboot/initrd.img .

[root@chenwei tftpboot]# cp /opt/yum/pub/p_w_picpaths/pxeboot/vmlinuz .

[root@chenwei tftpboot]# ls

initrd.img linux-install pexlinux.cfg pxelinux.0 vmlinuz

[root@chenwei tftpboot]# vi pxelinux.0

initrd.img linux-install/ pexlinux.cfg/ pxelinux.0 vmlinuz

[root@chenwei tftpboot]# mv pexlinux.cfg pxelinux.cfg

[root@chenwei tftpboot]# vi pxelinux.cfg/default

default linux

prompt 1 #prompt用来设置是否等待用户选择

timeout 6

display boot.msg

F1 boot.msg

F2 options.msg

F3 general.msg

F4 param.msg

F5 rescue.msg

label linux

kernel vmlinuz

append initrd=initrd.img

append initrd=initrd.img text

label ks

append ks initrd=initrd.img

label local

[root@chenwei tftpboot]# ls

[root@hb-node2 ~]# vi /etc/xinetd.d/tftp

# default: off

# description: The tftp server serves files using the trivial file transfer \

# protocol. The tftp protocol is often used to boot diskless \

# workstations, download configuration files to network-aware printers, \

# and to start the installation process for some operating systems.

service tftp

{

socket_type = dgram

protocol = udp

wait = yes

user = root

server = /usr/sbin/in.tftpd

server_args = -s /var/lib/tftpboot

disable = yes

per_source = 11

cps = 100 2

flags = IPv4

}

[root@hb-node2 ~]# service xinetd restart

Stopping xinetd: [FAILED]

Starting xinetd: [ OK ]

[root@hb-node2 ~]#

2.2 yum install dhcp

2.3 配置dhcp

[root@chenwei tftpboot]# cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf

cp: overwrite `/etc/dhcpd.conf'? y

[root@chenwei tftpboot]#

[root@chenwei tftpboot]# cat /etc/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

subnet 192.168.1.0 netmask 255.255.255.0 {

# --- default gateway

option routers 192.168.1.1;

option subnet-mask 255.255.255.0;

# option nis-domain "domain.org";

# option domain-name "domain.org";

# -- you understand Netbios very well

# option netbios-node-type 2;

allow booting;

allow bootp;

next-server 192.168.1.99; #指定tftp服务器

filename "/pxelinux.0"; #指定启动文件

range dynamic-bootp 192.168.1.80 192.168.1.90; #分配IP地址

default-lease-time 21600;

max-lease-time 43200;

# we want the nameserver to appear at a fixed address

host ns {

next-server marvin.redhat.com;

hardware ethernet 12:34:56:78:AB:CD;

fixed-address 207.175.42.254;

}

[root@chenwei tftpboot]#

[root@chenwei tftpboot]# service dhcpd restart

Starting dhcpd: [ OK ]

三编辑kickstart文件

[root@chenwei tftpboot]# yum install system-config-kickstart

[root@chenwei ~]# more /opt/yum/ks.cfg

#platform=x86, AMD64, or Intel EM64T

# System authorization information
